Despite the continuous asymmetrical power relations between the Global North and South, the “global race for talent” is no longer a privilege enjoyed only by developed countries. Comparative analysis of policy content and effectiveness has attracted increasing interest. The examination of policy initiatives resulting in return migration of highly‐skilled migrants from the Global North to the Global South, however, remains inadequate. In this article, we provide a comparative analysis of policies targeting high‐level Chinese and Indian professionals including full‐time returnees. Two key differences in policy instruments and outcomes in the two countries are identified and they have implications for migration policies in other countries in the Global South and North. 相似文献

Drawing from literature regarding public engagement, the Elaboration Likelihood Model (ELM), computer-mediated communication research, and emotion psychology, this study examines the effects of companies’ social media communication strategies on public engagement behaviors as indexed by post likes, shares, and comments. Specifically, it investigates how corporate Facebook posts’ functional traits (functional interactivity and vividness) and emotional traits (emotion presence, valence, and strength) impact public engagement online. Through data mining and computer-assisted sentiment analysis of 33,379 posts from 106 Standard & Poor 500 companies’ Facebook accounts, this study finds a negative effect of functional interactivity but a positive effect of vividness on engagement. It also shows that emotional traits overall yield stronger public engagement outcomes. Two-way interactions between emotional and functional features are also detected. Theoretical and practical implications are discussed. 相似文献

We present a theoretical model of Rabin’s famous calibration paradox that resolves confusions in the literature and that makes it possible to identify the causes of the paradox. Using suitable experimental stimuli, we show that the paradox truly violates expected utility and that it is caused by reference dependence. Rabin already showed that utility curvature alone cannot explain his paradox. We, more strongly, do not find any contribution of utility curvature to the explanation of the paradox. We find no contribution of probability weighting either. We conclude that Rabin’s paradox underscores the importance of reference dependence.

How does Chinese society maintain its orderly operation and show stability and harmony to the utmost while China rapidly transforms its economic system and international circumstances become increasingly complicated? This is an important question that this essay tries to answer, and the analysis mainly involves the exploratory practice of the transformation of Chinese social governance. This exploratory practice is a process through which China constantly breaks through the traditional blockades of vested interests, overcomes newly formed challenges, and forms a new Chinese-style “one axis and multiple components” pattern of social governance during its rapid re-establishment of both social relationship structure and social psychology order on the unbalanced and insufficient conditions of development within its vast territory. During this process, the constant return to the CPC’s mass line, as well as the “mechanism of reversed transmission of pressure,” the “anticipation-led mechanism” and the “mechanism of turning crisis into opportunity” that the CPC has improved during its long-term revolutionary struggles and its deepening of reform and opening-up, has played an important part. The simplistic duplication of Western theoretical analytic paradigms cannot explain the experiential mechanism for the transformation of social governance, which is peculiar to China. The creation of research framework of “system and life” is just an effort for comparison and dialogues with Western classical theories. It is not only helpful for the development of sociology about Chinese transformation, but will provide new knowledge for worldwide social transformation. 相似文献

This study examined biological sex differences in the development of mild cognitive impairment (MCI) and probable Alzheimer’s disease (AD) development as predicted by changes in the hippocampus or white matter hyperintensities. A secondary data analysis of the National Alzheimer’s Coordinating Center Uniform Data Set was conducted. We selected samples of participants with normal cognition at baseline who progressed to MCI (n = 483) and those who progressed to probable AD (n = 211) to determine if hippocampal volume or white matter hyperintensities (WMH) at baseline predicted progression to probable AD or MCI and whether the rate of progression differed between men and women. The survival analyses indicated that changes in hippocampal volumes affected the progression to probable AD (HR = 0.535, 95% CI [0.300–0.953]) only among women. White men had an increased rate of progression to AD (HR = 4.396, CI [1.012–19.08]; HR = 4.665, 95% CI [1.072–20.29]) compared to men in other race and ethnic groups. Among women, increases in hippocampal volume ratio led to decreased rates of progressing to MCI (HR = 0.386, 95% CI [0.166–0.901]). Increased WMH among men led to faster progression to MCI (HR = 1.048. 95% CI [1.011–1.086]). Women and men who were older at baseline were more likely to progress to MCI. In addition, results from longitudinal analyses showed that women with a higher CDR global score, older age at baseline, or more disinhibition symptoms experienced higher odds of MCI development. Changes in hippocampal volumes affect the progression to or odds of probable AD (and MCI) more so among women than men, while changes in WMH affected the progression to MCI only among men. 相似文献

白寿彝的民俗学研究表现在两个方面,一是收集整理地方文化中的民俗资料,二是进行相关的民俗现象研究。前者主要体现在对《开封歌谣集》的收集整理上,作为民国时期民俗学研究领军人物顾颉刚先生的学生,白寿彝通过编辑这部歌谣集,来反映诸多社会问题,表达对下层民众的关注,追求唤起民智的目标。后者先后体现在若干单篇论文中,其新中国成立以前论文主要是对封建迷信的歌谣观的梳理,特点是多取材于正史;其新中国成立以后论文主旨在于辨析民俗学中的传说思想,特点是取材于当代人的研究成果和充分利用传世文献,同时批评相关无学理意义的论断。这两方面的民俗学研究体现出白寿彝在民俗学理论方面的深厚修养,以及民俗学与历史学密切结合、关注下层民众、适应时代发展需要的高度自觉,至今具有一定的示范和借鉴价值。 相似文献

从“3Q大战”“3百大战”到天猫京东“二选一”事件,超级网络平台实施限制交易行为的现象越演越烈,也成为当前互联网领域的反垄断难题。我国反垄断法律法规在对网络空间的相关市场及市场支配地位的认定上存在适用困境,超级网络平台滥用市场支配地位的行为无法被认定且无法有效规制的现象长期存在。为规范超级网络平台的经营行为,应当调整《反垄断法》关于相关市场与市场支配地位的认定规则,将反垄断案件纳入公益诉讼范围,采取国家诉讼和私人诉讼并行的双重诉讼机制,减轻原告举证责任负担,同时将《反垄断法》与《电子商务法》衔接适用。 相似文献
